The article describes the process for Linux users, but GParted can partition any drive using the Live CD, regardless of your operating system. Ever since we started posting about multiple OS installs, from dual-booting XP and Vista to triple-booting XP, Vista, and Ubuntu, GParted has been my go-to partitioner. It's free, and since it's embedded on a Live CD, GParted works anywhere you can boot from a CD.
